Warning about the approach of the Hour

Allah is informing about the approach of the Hour in the past tense in Arabic in order to confirm that it will undoubtedly come to pass. This is like the following Ayat, in which the verbs appear in the past tense in Arabic:

اقْتَرَبَ لِلنَّاسِ حِسَـبُهُمْ وَهُمْ فِى غَفْلَةٍ مُّعْرِضُونَ

The Name of the Surah

This Surah has been called Al-Nahl, that is, the honey bee because it mentions it as a unique Divine marvel. Another name for this Surah is Surah Al-Ni` am. (Qurtubi) The word Ni'am is the plural of Ni'mah (blessing) because the great blessings of Allah Ta’ ala have been particularly mentioned in this Surah.
